This article applies recent advances in productivity and efficiency measurement to the evaluation of skillbiased technical change. Using the general index approach we are able to establish an explicit and unconstrained time path for nonneutral technical change between production and...

Relative wages have been remarkably rigid for the last two decades in Danish manufacturing despite large shifts in relative employment from unskilled labor towards skilled and educated labor. Assuming capital-skill complementarity and fixed relative wages as a consequence of labor market...

Different empirical studies suggest that the structure of employment in the U.S. and Great Britain tends to polarise into good and bad jobs. We provide updated evidence that polarisation also occurred in Germany since the mid-1980s until 2008. Using representative panel data, we show that this...

This paper reviews the literature on two-sided atomeless assignment models of workers to tasks. Using simple parametric examples, the fundamental differences between the comparative advantage and the scale of operations models are illustrated. Holding the distributions of abilities and tasks and...

This study attempts to explain why the transition to a market economy is skill-biased. It shows unequivocal evidence on increased skill wage premium and supply of skills in transition economies. It examines whether similar skill?favoring shifts in the Russian and U.S. economies are driven by the...

We offer an integrated explanation and empirical analysis of the polarization of U.S. employment and wages between 1980 and 2005, and the concurrent growth of low skill service occupations. We attribute polarization to the interaction between consumer preferences, which favor variety over...

This paper presents a general equilibrium assignment model of workers to tasks with endogenous human capital formation and multidimensionality of skills. The model has 2 key features. First, skills are endogenous and multidimensional. Second, two types of assignment occur, workers self-select...

This paper investigates the changes in the German wage structure for full-time working males from 1999 to 2006. Our analysis builds on the task-based approach introduced by Autor et al. (2003), as implemented by Spitz-Oener (2006) for Germany, and also accounts for job complexity. We perform a...

Wage inequality in Portugal increased over the last quarter of century. The period from 1982 to 1995 witnessed strong increases in both upper- and lower-tail inequality. A shortage of skills combined with skill-biased technological changes are at the core of this evolution. Since 1995,...
